INSPECTION PROCEDURE

NOTICE:
When replacing the skid control ECU, perform initialization of linear solenoid valve and calibration Initialization.

PROCEDURE

1. INSPECT BRAKE MASTER STROKE SIMULATOR CYLINDER ASSEMBLY

(a) Disconnect the brake master stroke simulator cylinder assembly connector.

(b) Measure the resistance according to the value(s) in the table below.

Resistance:

NG -- REPLACE BRAKE MASTER STROKE SIMULATOR CYLINDER ASSEMBLY
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO BRAKE MASTER STROKE SIMULATOR CYLINDER)

(a) Disconnect the skid control ECU connector and brake stroke simulator cylinder assembly connector.

(b) Measure the resistance according to the value(s) in the table below.

Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. RECONFIRM DTC

(a) Clear the DTC Electronically Controlled Brake System.

(b) Turn the engine switch on (IG).

(c) Check if the same DTC is recorded Electronically Controlled Brake System.

HINT
Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.

Result:

B -- REPLACE SKID CONTROL ECU

A -- END
